More Than an Attorney—A Trusted Advocate

Ms. Hartog is a true advocate for both children and her clients. She fight tirelessly for the best interests of children while recognizing the emotional toll divorce can take on families. Her compassion, support, and dedication make clients feel heard, understood, and cared for throughout the entire ...process. Anyone looking for an attorney who combines fierce advocacy with genuine empathy will be in excellent hands!!

Diane will handle all complexities of your case with care and dedication.

Diane has represented me through two divorces over the past several years, and she has done an outstanding job. She protected my interests every step of the way and helped me avoid situations that could have placed me at a significant disadvantage. I highly recommend Diane. She is aggressive when ...it matters, thoroughly prepared, and never backs down when opposing counsel makes false or misleading statements. She is absolutely fearless in the courtroom. While I've seen other attorneys become intimidated by a tough judge or a confrontational opposing party, Diane remains calm, confident, and focused. She stands her ground, advocates relentlessly for her clients, and consistently fights for the best possible outcome.

Love her!

Not only is Diane compationante and understanding, she truly has your best interests in mind when you are her client. Diane has represented me on 2 separate occasions now. Divorce with custody and then an emergency Custody hearing. She has become not only my attorney but also a friend I proudly cal...l family. I have referred more clients then I can count to her! Love her!

Highly Recommended

Diane has been my divorce Attorney throughout my complicated dirvorce with my deadbeat husband and dad. She has been there for me to listen and guide me and my children during this emotional time. Her knowledge, personality, and fight are the reason the judge has ruled in our favor after every court ...hearing so far. I am very pleased with the service she has provided me and my children. Diane and her staff have been welcoming and responsive to my calls, emails, and questions in a positive and supportive manner. Thank you so much for helping me comtinue to get thru such a difficult time in my life. I fully trust that we will continue to have judgements in my favor and I am glad you are in my corner. I would highly recommend Diane and her office to anyone in the midst of a divorce.

I'd re-hire her in a heartbeat.

I hired Ms. Hartog to represent me in my divorce. I can honestly say that it is a shame she does not practice more areas of the law because I would prefer to have her team handle all of my affairs. She is fair and honest, and her fees are very reasonable. I have felt very comfortable with her and ...with her staff as they have all gone above and beyond to handle my case with care. After having read the last two reviews, I can hardly believe they were talking about the same attorney, as this was exactly the opposite experience I had when represented by Ms. Hartog. I make it a point to refer all of my friends, family and acquaintances to her if they happen to need a lawyer who handles family law. And the feedback I get from them is the same satisfaction that I have had in dealing with her firm.
